A radiation image reading apparatus using a storage phosphor plate as a radiation image record is disclosd which includes a light beam scanning device, detection device and control device. The light beam scanning device generates a laser beam and scans the phosphor plate with the laser beam. The detection device detects a phosphor light from the phosphor plate generated by the irradiation of the laser beam and outputs an electrical image signal corresponding to the image information recorded at each of the pixels of the plate. The control device includes an optical shutter which is controlled so that the light beam from the scanning device is provided to generate only one beam spot for each of the pixels of the plate.
